A re-spelling of the F word used to get around old online forums that would auto-censor other more common misspellings like fuk, fukk, fook, and even fuak. Fuark was the only way to say the F word on these forums. A well-known forum that did this was bodybuilding.com, which is where this phrase took off, especially when the legendary Zyzz started actually saying it out loud in his YouTube videos.
"I can't even lift light weight today, what the FUARK"
